Frequently Asked Questions

Which baking calculator should I use?
Build when you need a full pizza recipe from pan size or dough weight (Pizza Dough). Convert when the recipe’s units or ingredients aren’t what you have (Yeast Conversion, Weight Chart, Flour Protein). Control when you’re mixing or fermenting (Leavening, Desired Dough Temp, Bulk Fermentation). Compare when two recipes look similar and you need the real difference.
What is the difference between the Leavening Calculator and Yeast Conversion?
Use Leavening to size commercial yeast or sourdough starter from fermentation time and temperature. Use Yeast Conversion when you already have a yeast amount and need to swap Instant Dry, Active Dry, or Fresh, or convert grams to teaspoons.
How do I scale a recipe I already saved?
Open the recipe and change its batch size.
How do I scale a recipe to fit different baking pans?
Use pan-size scaling on any saved recipe. Pick your source pan and target pans, and Bakers Math calculates the area ratio and divides the dough weight evenly across each pan.
How do I compare two baking recipes?
Use Recipe Compare to put two recipes side by side in baker's percentages. It highlights differences in hydration, salt, and preferments regardless of batch size.
How do I convert cups to grams?
Use the Ingredient Weight Chart. Pick the ingredient, enter cups, tablespoons, or teaspoons, and get grams — or go the other way from a weight.
